Organic Control of Cherry Fruit Fly

The active ingredient spinosad, a microbial insecticide, was tested for efficacy against cherry fruit fly. Several formulations were tested. The GF-120 product, a combination of spinosyn and a feeding attractant, proved very effective. A new system of control using point sources versus complete canopy cover was developed. The use of GF-120, an organically approved material, for cherry fruit fly control has become widespread among cherry producers in the region, both conventional and organic. It is very effective, non-toxic to humans, low impact to beneficials, and low cost due to the low volume used and quick application.
